    I'm trying to remove my O2 sensors from my rear manifold and downpipe and transfer them to my headers. But as I'm sure you know these things are really stuck in there. Is this more headache than it's worth?

    They're not that bad to get off. Just use the correct O2 sensor socket and some PB blaster or what not. Everyone I've done came right out without any issue.

    i had the right socket, it stripped the nut on the sensor. a lot of guys never get it out unless you heat the piss out of it.
